There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.

Another way is energy conservation ( 节能 ), which means using energy more efficiently ( 有效地 ). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.

Finally, renewable energy sources are used even though they are often expensive to develop. One form. of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped ( 压;抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.

1、How many ways of dealing with the energy problem are discussed in the text? ( )

A、Two.

B、Three.

C、Four.

D、Five.

2、From the text we learn that coal( ).

A、is quite easy to produce

B、is not used most efficiently

C、is the most common source of energy

D、could be renewed only by new technology

3、The writer tells about the "special houses" because they( ).

A、show the excellent skills of the builders

B、serve as an example of energy conservation

C、are heated by different sources of energy

D、are warmer than other types of houses

4、The underlined words "geothermal energy" in the third paragraph mean ( ).

A、renewable source

B、 underground source

C、 heat inside the earth

D、 temperature of the earth

5、At a place where the surface temperature is 15°C, how deep do you have to dig so as to get a temperature of 75 °C ? ( )

A、One km.

B、 Two km.

C、 Three km.

D、 Four km

  • 第2题:

    In some countries, _____ is called "equality" does not really mean equal rights for all people.

    (A) which (C) that

    (B) what (D) one

     

     


    选B


    这句话貌似定语从句。而实际上,前面的部分就是状语,后半句与countries没有修饰关系(因为1.后半句缺主语,但空格的位置用countries不能替换,否则语义不对。2.后半句不缺宾语。)所以后半句的()is called equality作主语.是主语从句。
    在选项中,只有what引导主语从句。
    意思:在一些国家里,所谓平等,并不意味着所有公民的平等权利

  • 第5题:

    It's said that he's looking for a new job, one_________ he can get more free time.

    A.when
    B.where
    C.that
    D.which

    答案:B
    解析:
    考查定语从句。one是a newjob的同位语,同时one是先行词,后面是个定语从句,由于定语从句he can get more free time不缺少任何成分,说明空格处在从句中作状语,需要用where引导,意为“从新工作中获得更多的自由时间”。如果选which的话,应该是one(a job)from which he can get more free time,故选B。
